The purpose of the community health assessment is to learn about the community: the health of the population, contributing factors to higher health risks or poorer health outcomes of identified populations, and community resources available to improve the health status. Community health assessments describe the health of the population, identify areas for health improvement, identify contributing factors that impact health outcomes, and identify community assets and resources that can be mobilized to improve population health. Community health assessments are developed at the Tribal, state, and local levels and cover the jurisdiction served by the health department. A community health assessment is a collaborative process of collecting and analyzing data and information for use in educating and mobilizing communities, developing priorities, garnering resources or using resources in different ways, adopting or revising policies, and planning actions to improve the population’s health. The development of a community health assessment involves the systematic collection and analysis of data and information to provide a sound basis for decision-making and action. Community health assessments are conducted in partnership with other organizations and members of the community and include data and information on demographics; socioeconomic characteristics; quality of life; community resources; behavioral factors; the environment (including the built environment); morbidity and mortality; and other social, Tribal, community, or state determinants of health status. The Tribal, state, or local community health assessment will be the basis for development of the Tribal, state, or local community health improvement plan.
